Do you know about the pig body reddening caused by this condition? Can you treat it?
Pig eperythrozoonosis is an infectious disease caused by Eperythrozoon suis of the order Rickettsiales parasitizing red blood cells or plasma. Pigs of all ages are susceptible to the disease, with piglets having a relatively high morbidity and mortality rate. It occurs mostly in summer and autumn, especially in hot and humid weather, and is relatively less common in winter. In recent years, whether in backyard pig farming or large-scale pig farms, it has frequently occurred, posing a serious threat to public health and bringing great economic losses to the pig industry. (1) Symptoms Affected pigs commonly show depression, complete loss of appetite, and a body temperature rising above 40°C. The disease course is long, with visible mucous membranes pale and jaundiced, and some pigs' skin color also turns white. There are convulsions of the limbs, shivering, diarrhea, and feces that are dark yellow, viscous, and have a fishy odor. In acute cases, death can occur within 1-3 days. When sows are infected, they mostly show fever and refusal to eat, jaundice, anemia, and emaciation leading to failure to come into estrus or repeated returns to estrus after mating without conception.
  　　 (2) Diagnosis Based on the epidemic season, the characteristics of the disease, and clinical symptoms, when pig eperythrozoonosis is suspected, draw about 1 mL of blood from a pig suspected of having eperythrozoonosis and make a smear, dilute it 10-fold with normal saline and mix evenly, cover with a coverslip, and observe under a microscope at 400-600 magnification. If moving organisms of various shapes are found on the surface of red blood cells and in the plasma, a diagnosis of pig eperythrozoonosis can be confirmed. Based on my own clinical practice, the accuracy rate is over 95%. (3) Prevention 1. Strengthen feeding management, improve barn sanitation, and eliminate stress factors. 2. In summer and autumn, frequently spray insecticidal drugs to prevent insects from biting the pigs. 3. When carrying out management procedures such as preventive injections, ear tagging, and castration, instruments should be replaced and strictly disinfected. (4)Treatment For this disease, early detection, early diagnosis, and earlytreatmentare needed so that the condition can be brought under control in time and losses reduced. First, affected pigs should be penned together and isolated from healthy pigs, and dead pigs should be subjected to harmless disposal. 1. Berenil, at 5 mg/kg body weight, intramuscular injection once a day for 3 consecutive days; when the dose is large, it is best to inject deeply at multiple sites. 2. Sulfamonomethoxine, at 0.1 mL/kg body weight, intramuscular injection once a day for 3 consecutive days. 3. Oxytetracycline, at 15 mg/kg body weight, intramuscular injection once a day for 3 consecutive days. 4. During the recovery stage, commonly use hematinic, vitamin C injection, inosine injection, and vitamin B12 injection by intramuscular injection for 2 to 3 days, to achieve the purpose of resisting anemia and strengthening the body.
